CARCINOGENICIDADE DE HIDROCARBONETOS POLICÍCLICOS AROMÁTICOS
The assessment of the carcinogenic potential of polycyclic aromatic hydrocarbons (PAH) is obtained by a principal component analysis (PCA) and quantitative structure-activity relationship (QSAR) using hydrophobic (LogP), stereo and electronic parameters (
